Deprecated Linux networking commands and their replacements

"In my article detailing the command line utilities available
for configuring and troubleshooting network properties on Windows
and Linux, I mentioned some Linux tools that, while still included
and functional in many Linux distributions, are actually considered
deprecated and therefore should be phased out in favor of more
modern replacements.

"Specifically, the deprecated Linux networking commands in
question are: arp, ifconfig, iptunnel, iwconfig, nameif, netstat,
and route. These programs (except iwconfig) are included in the
net-tools package that has been unmaintained for years. The
functionality provided by several of these utilities has been
reproduced and improved in the new iproute2 suite, primarily by
using its new ip command. The iproute2 software code and
documentation are available from the Linux Foundation."
